Electron emission element |
摘要 |
An electron emission element includes an insulating substrate. A base electrode is formed on the insulating substrate. A plurality of emitters are formed on the base electrode and are arranged radially with respect to a given point. The emitters have wedge shapes with their respective tips facing inward. An insulating layer is formed on the substrate and the base electrode, and is spaced from the wedges of the emitters by given gaps. A control electrode is formed on the insulating layer for enabling electrons to be emitted from the tips of the wedge-shaped emitters.
